Why does nutrient broth go cloudy?

Nutrient broth can go cloudy due to the growth of bacteria or other microorganisms in the broth that cause a change in its appearance. The cloudiness may also be a result of the formation of bacterial colonies or biofilms within the broth.


Do you expect turbidity in the unsterilized nutrient broth that was incubated?

Yes, turbidity is expected in unsterilized nutrient broth that was incubated, as the presence of microbial growth will cause the broth to become cloudy due to the increase in cell density. The turbidity is a visible indicator of microbial growth in the broth.


Why is nutrient broth better than peptone broth?

Nutrient broth contains a wider range of nutrients, such as meat extract and yeast extract, making it more suitable for supporting the growth of a variety of microorganisms. Peptone broth, on the other hand, primarily provides amino acids and peptides, which may limit the types of microorganisms that can grow in it.


What will result when 1 to 5 agar is added to nutrient broth boiled and cooled?

The agar will solidify and form a gel-like substance in the nutrient broth. This agar-nutrient mixture is used as a solid medium for growing and isolating bacteria in a laboratory setting.


Function of nutrient broth?

There are various types of nutrient broth, some selective, some not so. They are basically a liquid culture medium to enhance the growth of mircoorganisms from a sample, be it a human clincal sample, food, environmental sample or whatever. After the nutrient broth has been inoculated with the foresaid sample, it is generally incubated for a given length of time to encourage the growth of whatever is in the sample then identified.

How do you prepare LB broth without carbon source?

To prepare LB broth without a carbon source, omit the addition of glucose or any other carbon source from the recipe. Simply combine the other ingredients such as tryptone, yeast extract, and sodium chloride with water, and then sterilize the broth by autoclaving. This broth can be used for bacterial growth or protein expression in low-nutrient conditions.
